These metallic cables are prepared in a plastic shrouding with grease. Each location host between 11 to 15 cables meaning a total of 114 km of cables and 20 tons of surrounding concrete. Such technology allows to check the tension of the cables and eventually stretch the cables during the life of the reactor.

Irradiation Devices News

MICA Irradiation Device

MICA is a capsule type experimental device whose objective is to study structural materials behavior under irradiation for LWR reactors (temperature : 300-450°C maximum).The device, using a static thermal diffuser NaK is located in the JHR core. MICA design strongly use the one from the CHOUCA device used many times in OSIRIS reactor.

MICA device has a long length (6,5 m) from which the in-pile part is made of external cladding (diameter 32 mm) and a sample-holder (useful volume : diameter 24 mm / length 600 mm).

The request temperature in the samples is mainly obtained by nuclear heating from the core and regulated through electrical elements axially inserted in the MICA structures.

Three MICA irradiation devices will be completed between 2016 and 2018, to be ready for the first loading in JHR.

For more information : recent presentation at FONTEVRAUD conference 2014 (English version)


The first version of experimental ADELINE loop will be dedicated to power ramp testing.

The experimental ADELINE loop will be able to reproduce various experimental irradiation scenarios with experimental fresh or pre-irradiated fuel rods, such as :
- Power ramp tests,
- Rod internal over-pressurization (“lift-off”),
- Rod internal free volumes gas sweeping,
- Fuel centre melting conditions approach.

It will be a one rod experiment where clad failure will be allowed during the test protocol.

A first version will be mainly dedicated to power ramps testing. This will make it possible to continue the service offer and to operate with an experimental quality at least as good as the one already offered by ISABELLE1 loop in OSIRIS reactor. That means a qualified thermal balance and a good precision of the clad failure time and consequently a good knowledge of the Linear Heat Generation Rate (LHGR) inducing the failure. Moreover, some enhancements will be added in order to make a quantitative clad elongation measurement during the power transient and to carry out multiple experiences during a reactor cycle. The manufacturing of this loop will start early 2013.

The device will accept different fuel samples types :
- PWR (including VVER type) and BWR fuel pellets from 5.5 mm up to 14 mm of diameter
- UO2 fuels up to 12% enrichment of U5
- MOX fuels up to 20% ratio of Pu/(U+Pu)
- Rod length up to 600 mm
- Fresh fuel as well as high burnup fuel up to 120 GWd/t

On 6th of July, the official call for bids for the detailed design studies and manufacturing of the whole ADELINE experimental device (out-of-pile and in-pile parts) has been launched. Technical and financial offers are expected on 1st October 2012.

MADISON device: The kick off meeting for the detailed design, manufacturing and assembly phase took place on October 24th 2011.

In parallel to the construction of the JHR facility, CEA is developing experimental equipments that will allow performing irradiation experiments for clients from the nuclear industry. The MADISON device (Multirod Adaptable Device for Irradiations of LWR fuel Samples Operating in Normal conditions) is one of these tools that will be implemented inside the reactor building. It wiIl reproduce the neutron flux, thermal-hydraulics and chemical conditions of LWR (Light Water Reactor) power reactors, to irradiate fuel samples products in normal operating conditions.

The technology of MADISON is inspired from existing devices under operation in the experimental reactor of IFE / Halden (Norway). The IFE institute (operating the Halden reactor) will perform the detailed design, manufacturing and assembly on site, of the experimental water loop, of a sample holder and the Instrumentation and control. The kick off meeting of the associated contract took place on October 24th 2011 in Halden site with representatives of IFE and CEA JHR project.

Training of the JHR International partners to French Rules regarding design and manufacturing of Mechanical components of Research Reactors

How to share good Industrial practices on experimental devices and NDE equipments between partners ? CEA with AREVA and EDF worked on this topic and has published a code validated by the French Safety Authority (English version published by AFCEN in 2012).

11 trainees have followed a training session to this code called RCCMRx, organised by AREVA-TA and INSTN from 12th to 14th October 2011 in Cadarache. The following organisations have participated : IAEC (Israël) NRG (Netherland) VTT (Finland) IFE (Norway) to this successful session.

CEA will continue to regularly propose such training session.

The development of JHR experimental devices offers a unique opportunity to develop a new generation of devices meeting up-to-date scientific and technological state of art as well as anticipated users’ needs.

Development of experimental devices and related programs requires international collaborations to benefit from the available large experience and to increase the critical mass of cross-disciplinary competences.

CEA with international collaborators is developing first fleet of experimental devices to be on the shelves for the start-up of the reactor (called devices under development) oriented on LWR support but also is preparing a second fleet of experimental devices (called devices under feasibility phase) more oriented on GENIV support. The slides linked give an overview of such developments.

Radio-isotopes for medical use News

It has been defined that the radio-isotopes will be located in the JHR beryllium reflector.

In order to increase the JHR means of radioisotopes production, without decreasing the global experimental capacity, the design of the JHR reflector was redefined by the beginning of 2011. Consequently, the irradiation devices will be placed on displacement systems in order to achieve the loading and unloading operations out of the neutron flux.

Four locations are devoted to the 99Mo production. The displacement systems should be well interfaced with reactor structures. They should be very robust. The irradiation devices are connected by hoses to a dedicated cooling circuit.

As radioisotopes production is an industrial process, equipment dedicated to this activity should be reliable for use over several decades. It will be one of the main criteria in the detailed studies phase.

International Seminar on JHR experimental capacities – March 2011

CEA organised on the 9th and 10th March 2011 a seminar of information and exchanges regarding the JHR experimental capacities currently under development but also under feasibility phase to be developed later on.

All the JHR Consortium members were present (DAE from India, NRI from Czech Republic, CIEMAT from Spain, SCK.CEN form Belgium, VTT from Finland, JRC from the European Commission, VATTENFALL from Sweden, EDF and AREVA from France).

Detailed presentations on the experimental devices devoted to fuel and material studies under irradiation have been done and very fruitful exchanges with the potential end-users led to optimise the JHR experimental capacity.

We can quote, as an example, the strong request form the participants to have highly instrumented experiments compared to existing ones.

Following the success of this seminar, it has been decided to hold it every year and to open it to non-consortium members.

About 30 doctors have participated on 1st June 2013 to the first seminar on nuclear medicine in Cadarache. The visit of the Cadarache Centre allowed to focus on JHR which will produce a significant amount of Radio-Isotopes for medical application. « The use of isotpotes for diagnostic and medical care is one of the main component of nuclear medicine as reminded by Dr Jean-Philippe Vuillez, CEO of the French society of Nuclear Medicine.

The use of such Radio-Isotopes as tracking molecules allow functional Imaging, biochemistry, cellular and molecular. It represents a non-invasive method to study metabolic processes, cellular and molecular in human body” (Atout Cadarache – july 2013)
